This commits adds the ability to set a would-be exit code
for the Deno process without forcing an immediate exit,
through the new `Deno.exitCode` API.
- **Implements `Deno.exitCode` getter and setter**: Adds support for
setting
and retrieving a would-be exit code via `Deno.exitCode`.
This allows for asynchronous cleanup before process termination
without immediately exiting.
- **Ensures type safety**: The setter for `Deno.exitCode` validates that
the provided value is a number, throwing a TypeError if not, to ensure
that
only valid exit codes are set.
Closes to #23605

This is a primordialization effort to improve resistance against users
tampering with the global `Object` prototype.

- Removes the origin call, since all origins are the same for an isolate
(ie: the main module)
- Collects the `TestDescription`s and sends them all at the same time
inside of an Arc, allowing us to (later on) re-use these instead of
cloning.
Needs a follow-up pass to remove all the cloning, but that's a thread
that is pretty long to pull

The format of the sanitizers will change a little bit:
- If multiple async ops leak and traces are on, we repeat the async op
header once per stack trace.
- All leaks are aggregated under a "Leaks detected:" banner as the new
timers are eventually going to be added, and these are neither ops nor
resources.
- `1 async op` is now `An async op`
- If ops and resources leak, we show both (rather than op leaks masking
resources)
Follow-on to https://github.com/denoland/deno/pull/22226
This moves the op sanitizer descriptions into Rust code and prepares for
eventual op import from `ext:core/ops`. We cannot import these ops from
`ext:core/ops` as the testing infrastructure ops are not always present.
Changes:
- Op descriptions live in `cli` code and are currently accessible via an
op for the older sanitizer code
- `phf` dep moved to workspace root so we can use it here
- `ops.op_XXX` changed to to `op_XXX` to prepare for op imports later
on.
Step 1 of the Rustification of sanitizers, which unblocks the faster
timers.
This replaces the resource sanitizer with a Rust one, using the new APIs
in deno_core.
This change:
1. Implements `Deno.FsFile.sync()` and `Deno.FsFile.syncSync()`.
2. Deprecates `Deno.fsync()` and `Deno.fsyncSync()` for removal in Deno
v2, in favour of the above corresponding methods.

This change:
1. Implements `Deno.FsFile.dataSync()` and `Deno.FsFile.dataSyncSync()`.
2. Deprecates `Deno.fdatasync()` and `Deno.fdatasyncSync()` for removal
in Deno v2, in favour of the above corresponding methods.
3. Replaces use of `Deno.fdatasync()` and `Deno.fdatasyncSync()` with
the above instance methods.

This commit brings back usage of primordials in "40_testing.js" by
turning it back into an ES module and using new "lazy loading" functionality
of ES modules coming from "deno_core".
The same approach was applied to "40_jupyter.js".

This commit removes some of the technical debt related
to snapshotting JS code:
- "cli/ops/mod.rs" and "cli/build.rs" no longer define "cli" extension
which was not required anymore
- Cargo features for "deno_runtime" crate have been unified in
"cli/Cargo.toml"
- "cli/build.rs" uses "deno_runtime::snapshot::create_runtime_snapshot"
API
instead of copy-pasting the code
- "cli/js/99_main.js" was completely removed as it's not necessary
anymore
Towards https://github.com/denoland/deno/issues/21137
This brings in [`display`](https://github.com/rgbkrk/display.js) as part
of the `Deno.jupyter` namespace.
Additionally these APIs were added:
- "Deno.jupyter.md"
- "Deno.jupyter.html"
- "Deno.jupyter.svg"
- "Deno.jupyter.format"
These APIs greatly extend capabilities of rendering output in Jupyter
notebooks.

Adds `buffers` to the `Deno.jupyter.broadcast` API to send binary data
via comms. This affords the ability to send binary data via websockets
to the jupyter widget frontend.
This commit improves async op sanitizer speed by only delaying metrics
collection if there are pending ops. This
results in a speedup of around 30% for small CPU bound unit tests.
It performs this check and possible delay on every collection now,
fixing an issue with parent test leaks into steps.
Disables `BenchContext::start()` and `BenchContext::end()` for low
precision benchmarks (less than 0.01s per iteration). Prints a warning
when they are used in such benchmarks, suggesting to remove them.
```ts
Deno.bench("noop", { group: "noops" }, () => {});
Deno.bench("noop with start/end", { group: "noops" }, (b) => {
b.start();
b.end();
});
```

Handles ASCCI espace chars in test and bench name making
test and bench reporting more reliable. This one is also tested
in the fixture of "node:test" module.
Chipping away at making tests faster. Appears we don't need double
timeout before sanitizing ops. This should cut baseline cost of running a test
by half.
Closes #17589.
```ts
Deno.bench("foo", async (t) => {
const resource = setup(); // not included in measurement
t.start();
measuredOperation(resource);
t.end();
resource.close(); // not included in measurement
});
```
Closes https://github.com/denoland/deno/issues/15277
This commit adds a single "warmup" run of empty function when running
`deno bench`.
This change will break so-called "JIT bias" which makes V8 optimize the
first function
and then bail out of optimization on second function. In essence the
"warmup" function
is getting optimized and then all user benches are bailed out of
optimization.
